Homemade Alarm Clock Wakes You Up With A Slap In The Face [Video]

Simone Giertz decided that the most effective way to wake up in the morning is to have an alarm clock that slaps her in the face repeatedly with a rubber arm. To make it happen, she picked apart a clock, wired it to an Arduino UNO and controlled it via a 165 rpm brushless DC motor through a relay.

As you’ll see after the jump, the Wake-Up Machine may work too well. Not only did it smack Simone in the face, but it also ate her hair. That being said, watch out for some nsfw language.
